Abstract
The scattering of multi-charged ions (MCI) from the [100] surface of a RbI single crystal has been studied using a 120° back-scattering technique in the keV energy regime. Scattered charge-state distributions were measured as a function of the polar incidence angle and the target azimuthal orientation. Preliminary results indicate that “quasi-binary” collisions associated with scattering from a Rb or I site can be clearly distinguished for each scattered final charge state. The charge-state distribution and the relative Rb/I binary collision yields for scattered ions are found to depend on both the beam incidence angle and the target azimuthal orientation. The preliminary RbI(100) results are discussed in the context of earlier experimental and theoretical studies of MCI scattering on a Au(110) surface.
